Friday's sanitation procedure began with a basic cleaning with soap and water and has proceeded to disinfecting, according to Andrea Arcangeli, the vice director of Vatican City State's health and hygiene office.
Arcangeli said staff are disinfecting "the pavements, the altars, the sacristy, the stairs, practically all the surfaces," while taking care to not damage any of the basilica's artworks.
One of the additional health protocols St. Peter's Basilica may adopt as a precaution against the spread of coronavirus is checking visitors' temperatures, the Holy See press office said May 14.
Representatives of the four major Roman basilicas – St. Peter's, St. Mary Major, St. John Lateran, and St. Paul Outside the Walls – met May 14 under the auspices of the Vatican Secretariat of State, to discuss this and other possible measures to adopt.
Holy See Press Office Director Matteo Bruni told CNA that each papal basilica would adopt measures that reflected their "specific characteristics."
